<p>PURPOSE:To prevent the breakdown due to static electricity for attachment and detachment, by adding a metallic jig as a counter-measure against static electricity to a module which incorporates a memory consisting of a C-MOS, an LSI, or the like, a controlling circuit, etc. and is mounted freely attachably and detachably on a device main body. CONSTITUTION:A metallic jig 28 as a countermeasure against static electricity consisting of stainless with a thickness of about 0.2mm. is fixed to a lower cabinet 22 by an attaching metallic jig 29. A projecting part 34 makes the metallic jig 28 and the attaching metallic jig 29 conductive electrically to give a higher strength against static electricity. By this constitution, since static electricity accumulated in the human body is first flowed to the metallic jig 28 when the module is taken with hands for attachment or detachment, a circuit substrate 23, a C-MOS, and an LSI24 are protected from the breakdown due to discharge of static electricity.</p> |
